Response Permanent Redirect in MVC not issuing 301 or changing URL

I am converting an old ASP.NET web forms site to ASP.NET MVC 5. I would like to issue permanent redirects for the old page URLs.

Here is what I have done -

RouteConfig.cs:

routes.MapRoute("About_old", 
      "About/About.aspx", 
      new { controller = "Home", action = "About_old" });

HomeController.cs:

public ActionResult About_old()
{
   return new RedirectResult("/About", true);

   // I've also tried 
   // return RedirectToActionPermanent("About"); 
   // return RedirectPermanent("/About");
}

All attempts load the correct /About view, however the URL does not change, and I do not see a 301 code in the response. In other words, the URL is "localhost/About/About.aspx" and I expect it to be "localhost/About"

Complete Request/Repsonse from Chrome:

Request URL:http://localhost:55774/About/About.aspx
Request Method:GET
Status Code:200 OK

Request Headers
GET /About/About.aspx HTTP/1.1
Host: localhost:55774
Connection: keep-alive
Cache-Control: max-age=0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.117 Safari/537.36
Accept-Encoding: gzip,deflate,sdch
Accept-Language: en-US,en;q=0.8

Response Headers
Cache-Control:private
Content-Encoding:gzip
Content-Length:2284
Content-Type:text/html; charset=utf-8

Server:Microsoft-IIS/8.0
Vary:Accept-Encoding
X-AspNet-Version:4.0.30319
X-AspNetMvc-Version:5.1
X-Powered-By:ASP.NET

Nowhere do I see a 301 and the URL does not change. I have to think this has to do with how I am mapping the route of the old aspx page in RouteConfig.cs as all action methods have the same results. NOTE I have put a solution using global.asax below, however I would prefer it to work as I am attempting above, so I have not accepted my answer.

Am I doing something wrong or just missing something? How do I get the 301 to issue and URL to change?

Here is my solution (Global.asax)

protected void Application_PreRequestHandlerExecute(Object sender, EventArgs e)
        {
            string currentUrl = HttpContext.Current.Request.Path.ToLower();
            if (currentUrl.EndsWith("/about/about.aspx"))
            {
                Response.Status = "301 Moved Permanently";
                Response.AddHeader("Location", "/About");
                Response.End();
            }
        }

From answer here: Global 301 redirection from domain to www.domain
